so, do we just add networking.networkmanager.enable = true; to configuration.nix in nixos-generate-config? this is still a footgun if you use scripted networking options though | 04:45:54 |
 hexa | we are talking about new installs here | 04:46:10 |
| emily | I know | 04:46:25 |
| emily | I mean we still have to kill scripted networking | 04:46:34 |
| hexa | users who are not on scripted stuff to begin with don't need to migrate 🙂 | 04:46:48 |
| hexa | so this is a good change | 04:46:57 |
| emily | yes but the options are right there for them to set and when we flip useNetworkd it'll get turned on for new users too | 04:47:15 |
| emily | is my point | 04:47:18 |
 ElvishJerricco | Yea I'm pretty sure the scripted networking stuff is basically a noop if there is no networking.* configuration | 04:47:21 |
| emily | does useNetworkd avoid enabling networkd in that case? | 04:47:48 |
| ElvishJerricco | I mean this is already a threat with graphical installs since they enable networkmanager by default | 04:48:07 |
| emily | I think every ten years we should get a flag day jubilee where we can break anything we want arbitrarily and existing users just kind of have to figure it out | 04:48:08 |
| ElvishJerricco | and it's not been a problem | 04:48:11 |
| hexa | we ship with networkd either way | 04:48:11 |
| hexa | and it will have no config files, so it will not match anything | 04:48:19 |
| emily | In reply to @hexa:lossy.network
we ship with networkd either way not enabled | 04:48:21 |
| emily | but fair | 04:48:26 |
| hexa | yeah, not sure about enable toggle, but it will be a noop | 04:48:40 |

usedhcp is a fine default for a generic system with wired interfaces, regardless of which dhcp mechanism delivers the implementation. On a server, maybe you want static on at least some interfaces, so sure, you add config for those.
The issue is wireless. If a wireless interface appears, adding a dhcp client gets in the way of whatever mechanism the user is going to use to set ssid and keys, and so it has to get out of the way I thought our useDHCP default for networkd was wired only | 04:50:23 |
| ElvishJerricco | nope | 04:50:29 |
| emily | ok, well | 04:50:40 |
| ElvishJerricco | https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/tasks/network-interfaces-systemd.nix#L56-L75 | 04:50:50 |
| emily | what if we just introduce systemd.network.dwim = true; that ships the sane file for doing that that I think upstream has | 04:51:11 |
| emily | and put that in configuration.nix | 04:51:22 |
| hexa | lolsob … manual metric tuning | 04:51:25 |
| hexa | networkmanager to the rescue | 04:51:28 |
| emily | and then work on killing stuff | 04:51:35 |
| hexa | dwim? | 04:51:50 |
| hexa | do what i mean … TIL | 04:51:59 |
| emily | because I feel like "oh yeah to declaratively configure that you want to turn off NM that the generated config has and switch to this" is maybe not actually better | 04:52:08 |
